In peat grassland landscapes, extensive species-rich grassland is important for biodiversity. Vegetation, environmental conditions, management and production of 29 fields of 29 farmers have been analysed and related. In addition, integration in the farming system, farm economy and other factors were studied that have a role in the decisions of farmers in relation to species-rich grasslands. The report presents a typology of species-rich grassland and identifies opportunities for stimulating species-rich grasslands in peat meadow areas., In het veenweidegebied is extensief kruidenrijk grasland belangrijk voor de biodiversiteit. Van 29 percelen van evenzoveel boeren in de Alblasserwaard en Vijfheerenlanden zijn vegetatiesamenstelling, milieucondities, beheer en productie met elkaar in verband gebracht. Daarnaast is gekeken naar inpassing in de bedrijfsvoering, bedrijfseconomie en andere factoren die een rol spelen bij beslissingen van boeren ten aanzien van kruidenrijk grasland. Het rapport presenteert een typologie van kruidenrijk grasland en brengt kansen in beeld voor het stimuleren van kruidenrijk grasland in veenweidegebieden.

Rights and access to land are major pressing issues among mainly first-generation agroecological farmers in the Netherlands. Due to short-term tenure contracts and high land prices, these farmers face an insecure future. Because of this, they are often unable to make long-term ecological investments, such as planting trees and taking measures to improve soil health. A growing group of farmers are devising new, more communal forms of land ownership and tenancy, that counter market forces and existing policies. In this article, we shed light on these farmers’ discourse and how it informs the construction of new forms of land ownership and tenancy. In the related research project written and led by farmers, information has been gathered in the form of meeting minutes, interviews covering problems and perspectives related to the land tenure regulation, and commons. This information has been systematized and validated by farmers. Agroecological farmers find themselves in an uncomfortable situation that is challenging in 2 ways. On the one hand, they are calling for revision of land tenure regulations to ensure long-term land contracts for their existence and on the other hand they are seeking to replace property rights in favor of more collective possession-based arrangements. Our analysis shows how a discourse of decommodification seems to underlie the strategies and practices implemented by farmers. It focuses on place-based developments to secure the autonomy of farmers and communities. We argue that, to safeguard the possession and use of land for agroecological farming in the future, both developments of land decommodification (long-term tenancy and commons) should be supported. This can be done by integrated policies on land sale and lease that align with the ecological carrying capacity and agroecological production capacity of land, and that ensure compensation for monetary downgrading of agricultural land.

Nitrogen fertilisation is a common form of agricultural intensification, aimed at increasing biomass, which can affect plant species diversity and ecosystem functioning. Using a systematic review and meta-analysis of nitrogen fertilisation studies in European permanent grasslands, we asked: (i) what relationship form exists between nitrogen application rate and change in plant diversity, compared to zero fertilisation controls; and (ii) how grassland, management and study characteristics affect this relationship. Meta-analysis of 34 control-treatment effects from 14 studies conducted across nine European countries revealed a negative linear relationship between nitrogen fertilisation rate and change in plant species richness, equivalent to approximately 1.5 species/m2 lost for every 100 Kg ha−1 yr−1 of nitrogen added. Fertilisation induced reductions in plant species richness were greater when defoliation rates were lower. We found some evidence that grasslands with a higher baseline plant diversity lost more species when fertilised compared to more species poor grasslands, although uncertainty was high. Due to the diverse grassland types included in the analysis, the variability in fertilisation-driven changes in plant diversity was high. We identified several remaining limitations to our understanding, including uncertainty about non-linear effects, which could aid efforts to optimise the trade-off of plant diversity and increasing grassland yields.

In an extensive systematic review of the literature on permanent grassland in Europe we show that reducing the management intensity of permanent grasslands and preventing the conversion of permanent grasslands to croplands secures the provision of multiple ecosystem services. The evidence is based on 696 out of 70,456 screened papers.

Permanent grasslands cover 34% of the European Union's agricultural area and are vital for a wide variety of ecosystem services essential for our society. Over recent decades, the permanent grassland area has declined and land use change continues to threaten its extent. Simultaneously, the management intensity of permanent grasslands increased. We performed a systematic literature review on the multifunctionality of permanent grasslands in Europe, examining the effects of land use and management on 19 grassland ecosystem service indicators. Based on the evidence in 696 out of 70,456 screened papers, published since 1980, we found that both land use change and intensification of management decreased multifunctionality. In particular, preventing conversion of permanent grasslands to croplands secured the delivery of multiple ecosystem services. A lower management intensity was associated with benefits for biodiversity, climate regulation and water purification, but impacted the provision of high-quality animal feed. Increasing the number of species in the sward enhanced multifunctionality of permanent grassland without significant trade-offs such as losses in production. Our review covered many aspects of land use, management and ecosystem services, but we also identified areas with no or only few studies. The most prominent gaps were related to comparisons between permanent and temporary grasslands, and effects of management practices on the provision of cultural values, and on erosion and flood control. We suggest that, despite apparent changes in human dietary preferences, the protection of permanent grasslands in Europe must be prioritised. At the same time, considering the need to reduce ruminant livestock's contribution to climate change, the time seems ripe to increase support for low-intensity grassland management to optimise the provision of essential ecosystem services from Europe's permanent grasslands.

The Ossekampen long term grassland experiment (Wageningen, The Netherlands) was started in 1958 in an extensively grazed species-rich grassland. The treatments consist of several combinations of nitrogen, phosphorus and potassium application. The measurements include above ground yields, soil quality and botanical composition.

This report provides answers to the research question posed by the Ministry of Agriculture of the Netherlands: Could Miscanthus, Silphium perfoliatum and fallow sown in with melliferous plants comply with the expectations of the EU greening policy to be added to the Dutch general list for ecological focus areas? In addition to that the Ministry wants to know if it will be wise to accept sunflowers in seed mixture of catch crops. Miscanthus should not be considered for the EFA list, whilst Silphium perfoliatum is a suitable permanent crop. A list of melliferous plants suitable for green fallow land practice is compiled based on pollen and nectar quality as well as the timing of flowering. Sunflowers bring an added value to catch crop seed mixtures.
